surface between helix and circle - it won't work!

I am trying to construct a solid between a cirular surface and a helix surface, but it just won't work for me. The helix is directly above the cirle, and it's a 360 degree 1-turn helix, which is must be.

 

So far I've tried using:

-Loft

-Extrude

-Most of the surf commands

When I extrude the face, and the solid it creates meets the other end of the helix, I get this message:

Does anybody know how to pull this off? Where is it that I go wrong?

And a slighly off-topic question: Is Autocad adviced for this kind of design work, or would another CAD software serve me better?

I think a turn of .99999999 would work, but would I be able to connect the surfaces afterwards so that it is a closed cylinder 1-turn helix afterwards?

 

Here is the .dwg file

This would be a fairly crude 'divide and conquer' meth that gives respectable results.

I would use Inventor rather than AutoCAD, but there is no reason you shouldn't be able to use AutoCAD.

 

You mention "surfaces" several times rather than "solids".  Are you familiar with the differences between surface and solid modeling?

Attach your *.dwg file here and end all doubt.

I am familiar with the basic differences between solids and surfaces. I just had the idea that it is possible to create a solid from the surface as soon as I had it, even though I wouldn't know exactly how to do it. The .dwg file was is attached to the reply in my reply to parkr4st.

 

I actually had trying out inventor in mind. I have to look into it as it might be a better starting point than jumping right into Autocad.

Woah, I'm impressed at how you pulled that off! I must learn how to be more creative next time.
